Hurricane Kenna, the sixteenth tropical disturbance of the 2002 eastern Pacific hurricane season, explosively intensified from a tropical storm to a Category 5 hurricane in less than 48 hours. On October 25, 2002, Kenna made landfall on the western Mexican coast as a Category 4 storm. Kenna was born in the warm tropical waters of the eastern Pacific south of Mexico on October 22 to become the strongest storm to threaten the Americas in 2002...

|Lightning Strike Patterns Over Oklahoma : Image of the Day - NASA -- Animation by Robert Simmon, courtesy of the Global Hydrology and Climate Center|
In this animation, lightning flashes -- recorded during the NASA Lightning Imaging Sensor's pass over storms moving through Oklahoma in October 1998 -- are overlaid on high-resolution infrared cloud-top data from the orbiting Tropical Rainfall Measuring Mission (TRMM) satellite. High flash rates visible in the heaviest storm areas may indicate the potential for tornado formation. With an optical sensor locked into geostationary orbit over the Earth, such useful information would be available con...

|Microwave Imager Measures Sea Surface Temperature Through Clouds : Image of the Day - NASA -- Image courtesy TRMM Project, Remote Sensing Systems, and Scientific Visualization Studio, NASA Goddard Space Flight Center|
This image was acquired over Tropical Atlantic and U.S. East Coast regions on Aug. 22 - Sept. 23, 1998. Cloud data were collected by the Geostationary Operational Environmental Satellite (GOES). Sea Surface Temperature (SST) data were collected aboard the NASA/NASDA Tropical Rainfall Measuring Mission (TRMM) satellite by The TRMM Microwave Imager (TMI). TMI is the first satellite microwave sensor capable of accurately measuring sea surface temperature through clouds, as shown in this scene...

|A Look Inside Hurricane Alma: Image of the Day - NASA -- Image and animation courtesy Lori Perkins, NASA Goddard Space Flight Center svs.gsfc.nasa.gov/ Scientific Visualization Studio|
Hurricane season in the eastern Pacific started off with a whimper late last month as Alma, a Category 2 hurricane, slowly made its way up the coast of Baja California, packing sustained winds of 110 miles per hour and gusts of 135 miles per hour. The above image of the hurricane was acquired on May 29, 2002, and displays the rainfall rates occurring within the storm. Click the image above to see an animated data visualization (3.8 MB) of the interior of Hurricane Alma...

|Seasonal Swings in Tropical Rainfall: Image of the Day - NASA -- NASA Image Of The Day|
Rainfall is the primary way the atmosphere spreads heat around. Not surprisingly, nearly two-thirds of all rain falls in the tropics, where incoming sunlight is steady year round. Sunlight evaporates water from the warm ocean and land surfaces. The water vapor holds on to the heat that drove its evaporation until it condenses back into rain drops and releases the heat back to the atmosphere. This perpetual cycle of heating, evaporation, condensation, and rainfall moves heat from one place on Ear...

|Heavy Rains Bring Flooding to Mindanao: Image of the Day - NASA -- Images produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC)|
Several days of heavy rains led to widespread flooding on the island of Mindanao, in the southern Philippines. The heaviest rains occurred on February 11-12, 2004, as a steady northeast airflow associated with the winter monsoon persisted across the region. These northeasterly winds interacted with the Diuata Mountains that stretch north-south along the eastern part of the island to intensify the rainfall...

|Rainfall Totals from Tropical Storm Bill: Image of the Day - NASA -- Images by Hal Pierce (SSAI/NASA GSFC), text by Steve Lang (SSAI/NASA GSFC)|
After coming ashore on June 30, 2003, just east of Morgan City, Louisiana, the remnants of Tropical Storm Bill continued to produce heavy rain through the southeastern United States and mid-Atlantic region as the system tracked northeastward across the country. The heaviest rainfall totals were along the Gulf Coast east of where Bill made landfall. Some areas between western Louisiana and the Florida panhandle received upwards of 10 inches of rain according to observations from the Multi-satelli...

June 1 marks the beginning of hurricane season. Every year, meteorologists strive to predict hurricane behavior to reduce risk to lives and property while also minimizing the costs associated with storm preparations and evacuations. Perfect predictions of hurricane behavior are still a thing of the future, but NASA scientists are combining observations from field campaigns and the Tropical Rainfall Measuring Mission trmm.gsfc.nasa.gov/ (TRMM) satellite with supercomputing modeling power to shed ...
